Litecoin — long called the “digital silver” — has strong developments lined up to ensure the token’s long-term growth, said founder Charlie Lee on Twitter earlier today.Some of those include a Litecoin-branded debit card, Grayscale’s Litecoin Trust, and the much-awaited rollout of MimbleWimble, the privacy implementation on Litecoin led by Grin developer David Burkett.Tons of great Litecoin news recently.• Litecoin Visa card• Grayscale Litecoin Trust (LTCN)• Privacy/fungibility with Mimblewimble testnet soon• Hashrate up 50% this year• Transactions up 100% this year• Total addresses up 400% since Aug 2017• $500M sent per day🐔🚀 pic.twitter.com/SK2rL4C0fw— Charlie Lee [LTC⚡] (@SatoshiLite) August 19, 2020Fundamental developments for LitecoinCharlie Lee pointed out the following developments for Litecoin today:Grayscale Litecoin Trust (LTCN)Litecoin Visa cardPrivacy/fungibility with Mimblewimble testnet soonHashrate up 50% this yearTransactions up 100% this yearTotal addresses up 400% since Aug 2017$500M sent per dayTogether, these represent increasing retail and technical activity for LTC, which serves as a meaningful metric for investors and fund managers to consider the currency as either a viable investment or a long-term currency alternative to fiat money.Earlier this week, crypto-asset fund Grayscale announced its Litecoin Trust (LTCN), an investment vehicle for accredited investors in the US and worldwide to gain exposure to LTC, without holding the currency itself.Investors can gain exposure to the price movements of $BCH and $LTC without the challenges of buying, storing, and safekeeping them directly via $BCHG and $LTCN, respectively. https://t.co/96ZSxVomjB— Grayscale (@Grayscale) August 17, 2020The Foundation also announced its native debit cards for the retail masses this month, these include innovative ones like the Ballet Litecoin Block card, a .999 fine silver card with a full block reward of 12.5+ LTC.Today on the #LiteningSeries livestream, we also announced the Ballet Litecoin Block in collaboration with @balletcrypto and @ltcpool.This is a .999 fine silver card with a full Litecoin block reward of 12.5+ LTC.
